*NOTE: For protection, the Davey pump motor is tted with an
automatic “over temperature” cut-out. Constant tripping of this
overload device indicates a problem eg. low voltage at pump,
excessive temperature (above 45

avoid possible injury from hot pressurised water. Unplug pump, relieve
pressure by opening a tap on the discharge side of the pump and allow
any hot water in the pump to cool before attempting to dismantle.

is switched off and lead unplugged. Electrical connections should be
serviced only by qualied persons.
During servicing, use only approved, non-petrochemical based oring
and gasket lubrication. If unsure, consult your Davey Dealer for advice.

sprays around the electrical components of this pump.
In accordance with AS/NZS 60335.2.41 we are obliged to inform you that this

plugs & associated seals from the suction and/or
discharge ports.
CAUTION: To prevent personal injury, ensure all water pressure is released
from the pressure system prior to work being performed.
